  Effect of ligand flexibility on coordination-driven self-assembly of Pt(II) metallacycles

  摘要：

  The effect of ligand flexibility on the self-assembly of Pt(II) metallacycles was investigated. Three diazopyridyl ligands with different flexibilities were used to synthesize three nanoscale supramolecular complexes via Pt(II) mediated self-assembly. With comparatively less flexible ligands, 4,4'azobispyridine (2) and pyridine-4-carbaldehyde azine (3), formation of [3+3] molecular triangles was observed; in contrast, the most flexible of the three ligands, pyridine-3-carbaldehyde azine (4), yielded the [2+2] molecular rhomboid. All three complexes were characterized by multinuclear NMR (H-1 and P-31) and HR-ESI-MS, and the structure of complex 7 was further established by X-ray crystallography. These studies clearly showed that increased ligand flexibility entropically favors the formation of smaller metallacycles as the ligand can reduce angular strain through bending or conformational change.

  基于腔体的配位笼的自组装和阴离子包封特性

  摘要：

  已经通过自组装程序合成了两种新型的基于腔体的协调笼 7a--j 和 8a--d。控制笼自组装 (CSA) 的主要因素已确定为 (i) 螯合配体和金属前体之间的 P--M--P 角接近 90 度，(ii) Pd 和 Pt 作为金属中心， (iii) 弱配位的反离子，和 (iv) 四齿空腔配体的预组织。量热测量和动态 (1) H 和 (19) F 核磁共振实验表明 CSA 是熵驱动的。平衡笼低聚物的温度范围由空腔组分的预组织水平决定。笼子 7d 的晶体结构显示存在单个被封装的三氟甲磺酸盐阴离子。来宾竞争实验表明，笼子 7b 的封装偏好，d 遵循 BF(4)(-) > CF(3)SO(3)(-) >> PF(6)(-) 在 300 K 的顺序。 ES-MS 实验与分子建模相结合为观察到的提供了基本原理封装选择性。遵循客体溶剂化焓的基本选择性模式会因腔的大小和形状而改变，仅在 BF(4)(-) 的情况下才允许辅助溶剂分子进入。

  12-NC-1-H–CB11F10– were prepared, and three of them were examined for complex formation with (Et3P)2Pt(II) and (Et3P)2Pd(II). Several stable internally charge-compensated zwitterionic complexes were obtained and characterized. RI-BP86/SV(P) calculations suggest that their dipole moments exceed 20 D. An attempt to measure the dipole moments in solution failed due to insufficient solubility in solvents of
